Q

Define absence, myoclonic, and tonic-clonic seizures.

A

ABSENCE: most common in children, loss of consciousness lasting a few seconds, them client resumes baseline neurological functions

MYOCLONIC: are brief, shock-like jerks of a muscle or a group of muscles. “Myo” means muscle and “clonus” (KLOH-nus) means rapidly alternating contraction and relaxation—jerking or twitching—of a muscle. Usually they don’t last more than a second or two.

TONIC-CLONIC: usually lasts 1 to 2 minutes, but no more than 5. Will see an aura.

  • Tonic: stiffening of muscles, loss of LOC, cessation of breathing
  • Clonic: rhythmic jerking, irregular respirations, biting of cheek or tongue, bladder and bowel incontinence may occur.

52
Q

Describe the method for assessing for a Romberg sign.

A
  1. The patient is asked to remove his shoes and stand with his two feet together. The arms are held next to the body or crossed in front of the body.
  2. The clinician asks the patient to first stand quietly with eyes open, and subsequently with eyes closed. The patient tries to maintain his balance. For safety, it is essential that the observer stand close to the patient to prevent potential injury if the patient were to fall. When the patients closes his eyes, he should not orient himself by light, sense or sound, as this could influence the test result and cause a false positive outcome.
  3. The Romberg test is scored by counting the seconds the patient is able to stand with eyes closed.
